Description

ChEBI: An onium cation obtained by protonation of ammonia. ammonium ion: The monovalentcation NH4+. It may be regarded asthe product of the reaction of ammonia(a Lewis base) with a hydrogenion. The ion has tetrahedral symmetry.The chemical properties of ammoniumsalts are frequently verysimilar to those of equivalent alkalimetalsalts.

Ammonium is an onium cation obtained by protonation of ammonia. It has a role as a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a cofactor. It is a nitrogen hydride, an onium cation and a monovalent inorganic cation. It is a conjugate acid of an ammonia.|Inorganic compounds that include a positively charged tetrahedral nitrogen (ammonium ion) as part of their structure. This class of compounds includes a broad variety of simple ammonium salts and derivatives.
